PISTON-PACKING.

SPECIFICATION forming part of Letters Patent No. 246,008, dated. August23, 1881.

Application filed July 7, 1881.

T 0 all whom "it may concern Be it known that I, ALBERT HAMPE, ofStaunton, in the county of Macoupin and State of Illinois, have inventedcertain new and useful Improvements in Piston-Packings, of which thefollowing is a specification.

This invention relates to an improved construction of piston-packing bywhich a uniform contact with the cylinder is obtained; and thein ventionconsists of radial arms which extend from a sleeve of the piston-rod andare adjustable thereon, the arms supporting the inner packing-ring, thesections of which are pressed outwardly by means of spiral or othersprings, which are seated on brackets or projections of adjoiningsections. The sections of the outer packing-rings are split and arearranged to break joint with the sections of the inner packing-ring.

In the accom tianying drawings, Figure 1 repremnts a- "erticaltransverse section of my improved piston-packing on line was, Fig.2. Fi2 is a plan view of the same, and Figs. 3 and 4 are modified forms ofthe springs employed for pressing the innerandouter packing-ringstightly against the cylinder.

Similar letters of reference indicate corresponding parts.

By referring to the drawings, A represents the piston-rod of my improvedpiston-packing, to the (sonically-tapering end of which onchead of thepiston is secured by a central hub or sleeve, a, and by a transverse keyin the usual manner. From the huba extend radial arms B, which arearranged atrightangles to each other and connected to the oppositepiston-head by fastening screw-bolts. The arms B carry on clamp-screwsslotted and radially-adjustable bearing-plates orabutments G,whicharerounded off at the outer ends, so as to bear against (No model.)

the inner surface of the inner packing-ring, D. The inner packing-ring,D, is composed of three or more sections, according to the size ofthepiston and cylinder, each section being provided near each end withan inwardlyprojecting bracket or other projection, (1. Between thebrackets (Z of two adjoining ringsections is arranged a spiral or otherspring,D, by which the ring-sections are pressed outwardly and againstthe outer packing-rings,E. The outer packingrings are so arranged thattheir sections break joint with those of the inner packing-ring, asappears clearly in Fig. 1. The four or more interior springs, D, exertjointly a uniform outward pressure upon the inner and outerpacking-rings, so as to press them tightly against the inner surface ofthe cylinder and form an intimate contact therewith.

Having thus described my invention, I claim as new and desire to secureby Letters Patent As an improvement in piston-packings, the

combination of a central hub or sleeve having radial arms and adjustablebearing-plates or abutments with exterior packing-rings and an interiorpacking-ring, the sections of which are provided withinwardly-projecting brackets or projections, and acted upon by spiral orother springs which are interposed between adjoining brackets of theinner sections, so that the inner and outer packing-rings are forced inoutward direction, substantially as and for the purpose set forth. Intestimony that I claim the foregoing as my invention I have signedmyname, in presence of two witnesses, this 30th day of June, 1881.

OZRO O. HEATH, OF PROVIDENCE, RHODE ISLAND.

AUTOMATIC FIRE-=EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 246,009, dated August23, 1881,

Application filed January 20, 1881.

To all whom it may concern:

Be it known that I, OZRO G. HEATH, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in AutomaticFire- Extinguishers; and I do herebydeclare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the artto which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to lettersor figures of reference marked thereon, which form ,,a part of thisspecification.

My invention relates to certain improvements in automaticfire-extinguishers.

Heretofore automatic fire-extinguishers provided with a distributercovered with a metal cup secured by-fusible solder have been bjected to,for the reason that the water in the pipes conducts the heat from thefusible solder through the conductivity of the surrounding metal. Thisis a serious objection, from the fact that the water in the pipes mustpractically be heated almost to the temperature required to fuse thesecuring-solder before it (the solder) will melt. This detracts from theprompt and effective working of the extinguisher at a given temperature.In some automatic fire-extinguishers this objection has been partlyovercome by interposin g non-conducting substances between the fusiblesolder and the fluid-supply in the pipes. In others a valve andvalve-stem have been employed, the valve held against the end of thebranch pipe and the stem passing through the distributer and secured toa cup on the outside thereof by fusible solder. The last mentionedcannot be used with a revolving distributor, and interferes with theeffective operation of a stationary distributer, in that it breaks theforce of the fluid-supply and tends to clog or stop the flow of water,more or less, from the perforated distributer.

Anotherandquiteimportant objection urged against automaticfire-extinguishers provided with a distributer covered with a cupsecured by fusible solder, or those employing a valve or cup secured toor in the branch pipe or (ModeL) pipes by fusible solder to hold incheck the fluid-supply, is that after a fire has occurred and theextinguishers have performed their work and the fluid-supply has beencut off from the system of pipes, the cups must be recovered from thedebris, the distributers removed from the branch pipes, and together beforwarded to the manufactory whence they were purchased to be repaired,during which time the fluid-supply is cut off from the building in whichthe fire occured, thus remaining unprotected; or, on the other hand, toprotect the building during this interval the owner thereof must besupplied with a duplicate number of distrihuters with the soldered cups,to be used in the place of those forwarded to the manufactory.

A more series objection urged against antomatic fire-extinguishersemploying a valve 01 valves secured to or in the. branch fluidsupplypipes by fusible solder is that after a fire has occurred the wholesystem of branch pipes, or that portion in which the "alves wereunseated. by the melting of the fusible solder, must he removed andshipped to the proper place to have the valves again secured in positionwith the proper solder, or an agent of such manufactory must visit thebuilding in which the fire occurred to replace the valves.

My invention has for its object the overcoming of all of theseobjections, to retain the cup of the distributer to its base, to permitthe easy, cheap, and prompt replacement of the cup over the distributor,and to secure the same, and to provide an effective revolvingdistributer which will, with the same fluidsupply pressure, throw saidfluid-supply a greater distance than is accomplished by otherdistributers.

To these ends my invention consists of the parts, substantially ashereinafter described, and fully set forth in the claims.

In the annexed drawings, Figure 1, Sheet 1, represents a side elevationof my improved automatic fire'extinguisher. Fig. 2 is a similar View,with the hinged cup thrown back to show the sprinkler. Fig. 3 is alongitudinal vertical section of the same. Fig. 4 is a transversevertical section through the line mm, Fig. l.
